Engine coolant and its related components is a vital fluid in any internal combustion engine, however it is one of the most neglected systems in the vehicle. The newest domestic automobiles do not have service indicators for engine coolant; which would allow the owner to service the fluid before any serious damage occurs from electrolysis and metal breakdown. The proposed Coolant Service Monitoring System (CSMS) will utilize sensors to monitor the pH of the coolant mixture, as well as the DC voltage of the coolant with respect to ground. By monitoring the pH and voltage, the sensors can notify the operator when unsafe coolant conditions are present. Ultimately, by preventing excessive corrosion and accelerated electrolysis, automobile owners can save hundreds if not thousands of dollars by not having to replace heater cores, expensive radiators, and water pumps with the CSMS implemented in the vehicle.
